Beta-blockers were not associated with depression and other psychiatric adverse events, although they may have a relationship with sleep disorders, according to a meta-analysis.

?-Blockers are important drugs in the treatment of cardiovascular diseases. They are suspected of inducing various psychiatric adverse events (PAEs), particularly depression, affecting cardiovascular morbidity and mortality. We performed a systematic search for double-blind, randomized controlled trials investigating ?-blockers to analyze the risk of PAEs or withdrawal of therapy due to PAEs.

Researchers extracted the frequencies of PAEs and rates of withdrawals and reviewed them to the number of exposed patients. For ?-blockers versus placebo or other active treatment, they calculated odds ratios for individual PAEs and withdrawal rates. We retrieved overall 285 eligible studies encompassing 53 533 patients.

The risk of bias was judged to be high in 79% of the studies. Despite being the most frequently reported PAE with a total of 1600 cases, depression did not occur more commonly during ?-blockers than during placebo. ?-Blocker use was also not associated with withdrawal for depression.

Similar results were obtained for comparisons against active agents. Among other PAEs, only unusual dreams, insomnia, and sleep disorder were possibly related to ?-blocker therapy. In conclusion, this analysis of large-scale data from double-blind, randomized controlled trials does not support an association between ?-blocker therapy and depression.

Similarly, no effect for ?-blockers was found for other PAEs, with the possible exceptions of sleep-related disorders. Consequently, concerns about ?-blockers’ impact on psychological health should not affect their use in clinical practice.
